How Hacktivism Affects Us All

By Robert Vamosi | 07 September, 2011 20:01

In December 2010, a group of nearly 3000 activists under the name "Operation Payback" launched online attacks against PayPal, MasterCard, and Visa, briefly knocking the three financial services' sites offline and preventing consumers from accessing ATMs or online banking services. The activists retaliated against the three companies for severing ties with WikiLeaks, an online repository for whistleblower data that had recently included thousands of secret communications from the U.S. State Department and other world governmental agencies. Nine months later more than a dozen people--most between the ages of 19 and 24--were arrested in connection with these denial-of-service (DoS) attacks, even as new attacks were hitting corporate, military, and government sites worldwide.

Don't Overload Your PC with Security Software

By Rick Broida | 07 September, 2011 04:27

Reader Steve uses a program called Vipre Premium to keep his PC secure. The suite offers anti-virus, anti-malware, anti-spyware, a firewall, e-mail protection--basically, the works.But Steve also runs Malwarebytes Anti-Malware. And Microsoft Security Essentials (though with real-time protection turned off). Steve's question: should he turn on MSE's real-time protection and "run it concurrently with Vipre?"Short answer: no. Definitely not. In fact, I'd say Steve is running too much security software as it is. And that's a common mistake.For starters, the Vipre suite is more than sufficient. I can see keeping Malwarebytes Anti-Malware on hand just in case some infection sneaks through, but if you're using the Pro version--which, unlike its freebie sibling, offers real-time scanning--then it's competing with Vipre. In fact, when you overlap security products like that, they can seriously impact system performance and even falsely recognize each other as being a threat.My advice: keep your security tools to a bare minimum. In fact, if you're running Windows 7 (which Steve is), you're already adequately equipped to handle the majority of security threats. Windows 7 offers a solid firewall, and its built-in Windows Defender should block most spyware and pop-ups.Meanwhile, Internet Explorer 9 provides robust protection against phishing, malware, and other browser-related threats. (In fact, some tests have shown it to be the safest browser, period.) Cap that off with Microsoft Security Essentials and browser plug-in Web of Trust, and you've got yourself a nearly bulletproof PC. (I speak from experience: that's my exact configuration, and I haven't had an infection of any kind, well, ever.)Bottom line: don't overdo the security software. Too much is not a good thing.Contributing Editor Rick Broida writes about business and consumer technology.

Warning: Tips for secure mobile holiday shopping

I’m dating myself, but I remember when holiday shopping involved pouring through ads in the Sunday paper, placing actual phone calls from tethered land lines to research product stock and availability, and actually driving places to pick things up. Now, holiday shoppers can do all of that from a smartphone or tablet in a few seconds, but there are some security pitfalls to be aware of.
